Answer:
408
Step-by-step explanation:
You would set up a proportion of 1/12 = 34/x. You would do the butterfly method and get 1x=408. Then divide 408 by 1 to get 408.
Answer:
408
Step-by-step explanation:
You see the rate is one out of twelve(1/12)
So if 1 now equals 34 (ALWAYS KEEP THE FRACTIONS BALANCED, WHAT YOU DO TO ONE SIDE YOU MUST DO TO THE OTHER)
so to get 1 to 34 you multiplied by 34. So do the same to 12 to get your total number or surveyed students.
